Building on windows

[campbellwmorgan]

I've written some code using this library which works brilliantly on linux, but I'm having some serious problems building it on Windows.

I've managed to build SRT fine and after a big struggle, I have managed to configure the lib and include folders correctly so that mingw64 can read them, however i'm getting the following error when running go build on my project:

# github.com/haivision/srtgo
..\..\vendor\github.com\haivision\srtgo\netutils.go:25:7: undefined: unix.AF_INET6
..\..\vendor\github.com\haivision\srtgo\netutils.go:30:7: undefined: unix.AF_INET
..\..\vendor\github.com\haivision\srtgo\netutils.go:56:57: undefined: syscall.SizeofSockaddrInet4
..\..\vendor\github.com\haivision\srtgo\netutils.go:69:57: undefined: syscall.SizeofSockaddrInet6
..\..\vendor\github.com\haivision\srtgo\srtgo.go:232:17: undefined: syscall.SizeofSockaddrAny

I don't know enough about the unix or syscall packages to know whether these can be called from windows at all. Am I making a build configuration mistake or is it simply that this library has not been written with windows in mind?

Many thanks in advance!

Edit: To give some context

OS: Windows 10 Go Version: 1.17.1 Pacman version v6.0.1 Libsrt tag v1.4.3 Gcc (Rev5, Built by MSYS2 project) 10.3.0 (via mingw64)

I've been digging a bit further, and the parts of the syscall package which are undefined here (https://cs.opensource.google/go/go/+/refs/tags/go1.17.1:src/syscall/ztypes_linux_amd64.go;l=311) have the following header

//go:build amd64 && linux
// +build amd64,linux

which makes me think that without modification, this library will never build on windows.

Try to build (& test) with the code from my branch, it's a bit of a hack, but it should hopefully work ;)
